[OT] Howto force gs to use BoundingBox

[Daniel Reuter <reuter@Uni-Hohenheim.DE>]

Hello there,

This is totally off topic, but does someone of you know, how to force
gs to render eps files only as large as the BoundingBox defines.
I mean, if I run gs on a eps file to render, say a jpeg or a png file,
I get a image sized as large as the default papersize (e.g. a4 or
letter). Unfortunately, the -sPAPERSIZE switch only allows fixed sizes 
and sometimes the contents of the page gets moved out of the shown area.
So how can I force gs to render a jpeg, which has EXACTLY the
boundaries defined by the eps BoundingBox?

Regards,
Daniel
